Cover art for Foot Shooter lyrics by Frightened Rabbit

it's about how he gets drunk and says things he doesn't mean to someone, probably a girl, but really could be anyone. so this song is written like when he's sober as a warning to the person not to take it personally, not to believe anything the singer says when they are drunk, to "thicken your skin" as he starts to "shoot myself in the foot again" by saying/doing these things. it might be that he gets drunk while out with his lady friend and starts shit with another guy (hence the line "say whatever i think, say it at him!") and eventually this turns into saying things he doesn't mean to her. i dunno. great song though.
